================================================================
Dear Bug Team!
I was using xemacs as normal, with several shell buffers open and
several text files. The process had been running for a couple of
weeks. It suddenly crashed with
Fatal error: assertion failed, file redisplay-output.c, line 1595, db->xpos >= 0 && db->ypos >= 0
Fatal error (6).
Your files have been auto-saved.
Use `M-x recover-session' to recover them.
Your version of XEmacs was distributed with a PROBLEMS file that may describe
your crash, and with luck a workaround. Please check it first, but do report
the crash anyway. Please report this bug by invoking M-x report-emacs-bug,
or by selecting `Send Bug Report' from the Help menu. If necessary, send
ordinary email to `crashes at xemacs.org'. *MAKE SURE* to include the XEmacs
configuration from M-x describe-installation, or equivalently the file
Installation in the top of the build tree.
*Please* try *hard* to obtain a C stack backtrace; without it, we are unlikely
to be able to analyze the problem. Locate the core file produced as a result
of this crash (often called `core' or `core.<process-id>', and located in
the directory in which you started XEmacs or your home directory), and type
gdb /u/avised/bin/linux/xemacs core
then type `where' at the debugger prompt. No GDB on your system? You may
have DBX, or XDB, or SDB. (Ask your system administrator if you need help.)
If no core file was produced, enable them (often with `ulimit -c unlimited'
in case of future recurrance of the crash.
Lisp backtrace follows:
next-command-event()
byte-code("..." [goal-column unread-command-events start-point last first mess age "<<< Press Return to bury the buffer list >>>" next-command-event ?\ nil th row electric-buffer-menu-select 2 -1 0 Electric-command-loop t electric-buffer-m enu-looper] 8)

call-interactively(electric-buffer-list)
# (condition-case ... . error)
# (catch top-level ...)
Sorry, no core file was written despite 'ulimit -c unlimited'; I'll
take this up with my sysadmin. But I hope the Lisp backtrace and line
number in the C source code will help you investigate.
If you don't want to make a big change to the stable xemacs release
perhaps the assertion could just be commented out, since crashing the
whole xemacs session because of this assertion failure is a bit
drastic and the assertion is probably doing more harm than good to
xemacs's stability.
